title = "Active 433 MHz-W UHF RF-powered chip integrated with a nanocomposite m-MWCNT/polypyrrole sensor for wireless monitoring of volatile anesthetic agent sevoflurane",
abstract = "Tiny remote sensors capable of monitoring gases and vapors are having greatest demand due to their potential applications in diverse research fields. In the present work, design and fabrication of an active wireless UHF (433 MHz) RF-powered sensing system for monitoring volatile organic compounds is presented. The developed sensor chip consists of a thin film of gas-responsive composite material, based on modified multiwalled carbon nanotubes (m-MWCNTs) and polypyrrole (Ppy), coated over two comb-like interdigitated gold electrodes. Wireless modules have been integrated with the chemical sensor chip (composite m-MWCNTs/Ppy) and RF components to detect volatile anesthetic agent, fluoromethyl 2,2,2,-trifluoro-1-(trifluoromethyl) ethyl ether (sevoflurane) is demonstrated.",

note = "Funding Information: We thank all the members of the Gas Metrology Group [G300], Center for Measurement Standards/National Measurement Laboratory, ITRI and Mr. Michael F. Huang, Chairman & General Manager and the members of U-CAN DynaTex Inc., Nankang Industrial Park, Nantou City, Taiwan for letting us utilize the facilities. Authors, THL & SLH would like to acknowledge the National Science Council (NSC) of Taiwan, ROC for the financial support to Department of Civil Engineering, National Chiao Tung University (NCTU), Taiwan in the form of a research project, Grant no. NSC95-2221-E-009-241-MY3. Authors, MC and RJW express thanks to Dr. B.Y. Wei of MCL/ITRI, Taiwan for kindly supplying us with the necessary MWCNTs as and when required. Funding Information: Murthy Chavali received his M.Sc. (Technology) in Chemistry (1994) from Jawaharlal Nehru Technological University, India and Ph.D. Technology (2000) from Technische Universit{\"a}t Wien, Austria in analytical chemistry and served as a postdoctoral scientist at Center for Instrumental Analysis, Kobe University, Japan, with Japanese National Scientific Fellowship (JSPS) supporting his research on NIR combustion sensors. Later he joined as a researcher for a short period at Precision Instrument Development Center (PIDC—now Instrument Technology Research Center, ITRC), under National Science Council (NSC), Taiwan R.O.C and moved to CMS/ITRI, Taiwan, in 2003 as a researcher in Sensors and Standards Group. Presently he is with private industry as R&D In-charge for Chemical Section. His research interests are optical waveguide technology, IR sensors, LIF, chip-based chemical and biochemical sensors (μ & η), development and application of spectroscopic techniques for the study of nanomaterials. His present research focuses on synthesis and fabrication of various organic, inorganic nanostructured materials, composites and nanosensor array technology, broadly, nanotechnology applications for gas and liquid sensors.
